BURLINGTON — A Wolcott man has pleaded not guilty to selling used vehicles he is alleged to have tampered with in order to get a better price.

Douglas Jordan, 40, was charged with fraud and firearms charges in U.S. District Court in Burlington on Thursday.

According to the U.S. Department of Justice, Jordan, doing business under the name Auto Credit Solutions, bought high-mileage used cars at auctions in Vermont and resold them. The department says Jordan would do things like removing or disabling warning lights for anti-lock brakes, air bags and check engine systems and is also accused of rolling back a truck’s odometer 100,000 miles so he could get a better selling price on the vehicles.

Jordan is also charged with having a firearm as a felon, as the department says he has a felony driving conviction in Massachusetts.
